' fabric curtain of an automobile.

' It has proven a matter of considerable difficulty to mount a window glass over an opening in the fabric curtain of an automobile, this being due' to the excessive weight of the glass, the unusual vibration of the ear and -the difficulty encountered in securing the window frameto the flexible fabric curtain. This invention has therefore for its prime purpose the provision of a window frame which will positively engage andbind the marginal edges of the curtain fabric around the opening in a secure and sightly manner, and at the same time rigidly support the window glass Another object of this invention is to provide a frame for the curtain window which will expose one of its members upon the outside of the curtain and will neatly cover and conceal a complementary frame member upon the curtain. It has a further object to provide a pair of com lementary frame members so construct ed t at they may be easily brought into their alined and assembled positions with relation to each other and the curtain and thus hold during the final clamping operation, thereby insuring that the frame may be accurately mounted in position and that the time consumed in assembling the frame may be greatly reduced when compared with the assembly time requiredin most other window curtains of common construction. Other objects will appear hereinafter.

The invention is illustrated by way of example in the accompanyingdrawings, in wluch- Figure 1 is a view in elevation illustrating a fragmentary. portion of a curtain with a window formed therethrough and encircled b the device with which the present inventlon is concerned.

Figs. 2 and 3 are perspective views illustrating the complementary frame members and their interlocking, centering and clamping elements. 1

Fig. 6 is a fragmentary view in perspective and section illustrating the manner in which the curtain fabric is secured to'the frame members.

Referring more particularly to the drawings, 10 indicates a fabric curtain, which, in the present instance, is composed of an outer sheet of fabric 11 and. an inner sheet 12. A window opening is formed through these sheets and may be of any desired configuration. Frame members 13 and 14 are provideclzto bind the marginal edges-of the fabric at the opening and also toserve as a rigid mounting for a .window glass 15.

The frame member 13 is preferably of polished ornickel-plated metal and is disposed on the outside of the curtain. As particularly shown in Fig. 4, a lip 16'is formed around theouter edge of this member and is adapted to lie in overlapping-relation to the outer edge of the complementary frame member 14 for a purpose which tive engaging means of the curtain by the will be hereinafter set forth. The inneredge of the frame member 13 is formed with a continuous recess 17 into which the outer edge of the window glass is adapted to seat. The flat face of this frame member is fitted with a series of fastening and centering studs 18 which extend perpendicularly therefrom and into openings 19 formed through the opposite frame member. These studs are threaded and receive countersunk clamping nuts'20 which act to bind the two frame members together and the fabric therebetween. Screws might be used, however, and the threads omitted from the studs.

The frame member 14 maybe of metal or ing from the fiat face of this frame member are a. series of pointed fastening pins :21 which are adapted to pass through the edges of the curtain fabric and into recesses 22 in the face of the frame member 13, thus securely engaging and locking the fabric in position.

In the application of this device to a window curtain the fabric sheet 11 is formed with an opening having the same dimensions. as the inside dimensions of the frame member 13. The sheet 12 is formed with an opening of somewhat smaller dimensions and the marginal edges of this opening are slit radially at suitable intervals to each other to insure that when the fabric is carried around the frame member 11 it will conform neatly to the frame member and lie fiat on the inner face thereof. Openings are then formed through the fabric sheet 11 to admit the studs 18. lhe frame member 13 may then be placed in position around the opening in the sheet 11 with its studs through the small openings and the frame member 14 placed in position with relation to the sheet 12 on the curtain. the curtain being brought around the member 11 and carried up to bring the pins 21 through certain of the tangs 23 formed by slitting the edge of the opening. when this has been done the two frame members may be readily assembled by placing the studs 18 through the openin 'slt and thereafter clamping them together by the nuts 20, thus simultaneously binding the edges of the fabric, clamping the window lass 15 in place and drawing the li 16 of t e outer frame member 13 in over apping relation to the frame member 14:. This last operation will act to seal the space between the two frame members and prevent the seepage of water down the fabric 11 and into the joint.

It will thus be seen that by the use of the curtain window here disclosed a window opening may be readily closed in a manner to securely clamp the window glass in posi tion, conceal the inner frame member, posi tirely hold the marginal edges of the curtain its 1. in combination with a cent said opening engaged between the inner faces of the frame sections, means to sscurc the sections together, and a hp 1 on the peripheral portion of the outer sc tion and projecting outwardly beyond inner face of said outer section and hating tree edge engaged with the curtain so a. to depress a .d form an angular in the latter which angular part is of substantially Zshape and is engaged with the periphery of the inner section and seals the joint be tween the two sections.

2. In combination with a curtain hari inner and outer fabric members with a w dow opening in each. a sectional frame, the inner fabric member extending over the outer face and inner edge and across the mner face of the inner section, and the outer fabric member being superimposed upon that part of the inner fabric member which engages the inner face of the inner section. a window glass seated on said superimposed portions of the fabric members, the. outer section being also seated upon said superimposed portions of the fabric members and having a cut-out on its inner circumference to receive the glass and having a marginal lip extending outwardly from the inner face thereof. said lip engaging the outer fabric member and forming an angular part in the latter. which angular part embraces the periphery of the inner section.

In testimony whereof I have hereunto my hand in the witnesses.
